The role of ethnicity in observers’ ratings of mother–child behavior.

This study examined the role of ethnicity in untrained observers’ ratings of videotaped mother–child interactions. Participants were Black, White, and Latino undergraduates (N = 109), who rated videotapes of 4 Black, 4 White, and 4 Latino mother–child dyads. Overall, participants of different ethnicities showed more similarities than differences in their ratings of parent–child behavior. There was, however, evidence that participant ethnicity and parent–child ethnicity interacted for ratings of child defiance/negative emotion. Black and White participants differed in their ratings of Black and White children’s defiance/negative emotion, with members of each ethnic group favoring children of their own ethnic group. Intergroup contact appeared to play a role in ratings of parent behavior among Black observers. Black observers who reported low intergroup contact tended to rate Black mothers high on strictness and low on permissiveness. More research is needed to better understand the role of ethnicity in observers’ ratings of parent and child behavior. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The influence of mother–child emotion regulation strategies on children's expression of anger and sadness.

In a sample of 153 children from preschool through second grade, relations between the use of emotion regulation strategy and children's expression of anger and sadness were coded during an observational task in which children were intentionally disappointed in the presence of the mother. Multilevel modeling was used to examine strategy use and current and subsequent expressions of anger and sadness. Results indicate that mothers' use of attention refocusing and joint mother–child cognitive reframing lead to lower intensity of expressed anger and sadness. Younger children expressed more sadness than older children, and maternal attention refocusing was less successful among older children than younger ones. Implications of these results for assessing the socialization of emotion regulation in preschool and school-age children are discussed.

Propositus with Weaver syndrome and his mildly-affected mother: implication of nontraditional inheritance?

AIMS AND BACKGROUND: Gliomas of the conus medullaris often show characteristic clinical, radiological, and intraoperative features which differ from gliomas involving other parts of the spinal cord. METHODS: Eight patients with histologically verified gliomas of the conus medullaris were diagnosed and studied. RESULTS: There were five men and three women ranging in age from 21 to 59 years. Predominant initial symptoms were back pain (4 cases) and leg weakness (4 cases). The most common findings on admission were flaccid paraparesis with impaired sensation and bladder dysfunction. Postoperative magnetic resonance (MR) images with more than 95% removal of a tumour were defined as "subtotal removal" (noted in 4 of 8 cases), and less than 95% as "partial removal" (4 of 8 cases). All patients had postoperative radiotherapy. During the follow-up period ranging from 3 to 10 years, there was no tumour recurrence or regrowth on MR images. CONCLUSIONS: The postoperative radiotherapy in gliomas of the conus medullaris where total resection is not possible seems provide a beneficial effect on preventing tumour regrowth.     

Child care and mother–child interaction in the first three years of life.

Relations between nonmaternal child care and ratings of maternal sensitivity and child positive engagement during mother–child interaction at 6, 15, 24, and 36 months were examined for 1,274 mothers and their children participating in the National Institute of Child Health and Human Development(NICHD) Study of Early Child Care. In longitudinal analyses that controlled for selection, child, and family predictors, child care was a small but significant predictor of maternal sensitivity and child engagement. For the whole sample, including families who did and did not use child care, more hours of child care predicted less maternal sensitivity and less positive child engagement. For children who were observed in child care, higher quality child care predicted greater maternal sensitivity, and more child-care hours predicted less child engagement. The effects of child care on mother–child interaction were much smaller in the analytical models than the effects of maternal education but were similar in size to the effects of maternal depression and child difficult temperament. Patterns of association with child care did not differ significantly across ages of assessment. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Eating problems and the observed quality of mother–daughter interactions among girls with type 1 diabetes.

This study examined how eating problems are linked to autonomy and intimacy in the observed interactions of 88 diabetic girls (M=14.9 years) and their mothers. On the basis of self-reported symptoms, teens were classified as having no eating problems (n=40), mild eating problems (n=30), and frequent eating problems (n=18). Mothers and daughters participated in 2 videotaped problem solving tasks (1 diabetes related and 1 a general parent-teen issue) that were rated with a macroanalytic coding system (Autonomy and Intimacy Rating System). Compared with interactions among mothers and daughters with no eating problems, interactions among mothers and daughters with eating problems simultaneously constrained the expression of autonomy and intimacy. Findings support clinical theory that links eating problems to emotional misattunement in the mother-daughter relationship, which is postulated to interfere with the teen's capacity for individuation.

Skewed autonomy–relatedness in preadolescents' conceptions of their relationships with mother, father, and best friend.

Healthy adaptation within all close relationships—whether with parents, friends. or romantic partners—involves striking a balance between connectedness to and independence from the relationship partner. For some individuals, adaptation within one or more relationships is skewed, or characterized by either an excessive concern for closeness that impedes autonomy (preoccupied stance) or an excessive concern for autonomy that inhibits closeness (avoidant stance). In this study with boys and girls aged 9–14 years, children who reported a preoccupied or avoidant stance toward their mother displayed increased social impairment in the peer group over time. There were predictable associations among children's stances toward mother, father, and best friend. Children resembled their best friend in relationship stance. The study illustrates the advantages of applying common relationship constructs (e.g., autonomy-relatedness) to the study of diverse close relationships.

Emotion regulation as a mediator of associations between mother–child attachment and peer relationships in middle childhood.

Although a link between attachment and peer relationships has been established, the mechanisms that account for this link have not been identified. The 1st goal of this study was to test emotion regulation as a mediator of this link in middle childhood. The 2nd goal was to examine how different aspects of emotion regulation relate to peer competence. Fifth graders completed self-report and semiprojective measures to index mother–child attachment, mothers reported on children's emotionality and coping strategies, and teachers reported on children's peer competence. Constructive coping was related to both attachment and peer competence, and mediated the association between attachment and peer competence, suggesting that emotion regulation is one of the mechanisms accounting for attachment-peer links. Constructive coping was more strongly associated with peer competence for children high on negative emotionality than for children low on negative emotionality.

Predicting boys' social acceptance and aggression: The role of mother–child interactions and boys' beliefs about peers.

Seven- to 9-year-old boys (N?=?177) and their mothers participated in this study in which the associations between boys' experiences with their mothers, their beliefs about familiar and unfamiliar peers, and their peer adjustment were examined across a 2-year period. Boys' negative behavior with mothers was associated with their having more negative beliefs about familiar and unfamiliar peers and with their being more aggressive and less well-liked. Beliefs about familiar peers predicted changes in boys' social acceptance, whereas negative beliefs about unfamiliar peers predicted changes in aggression. In addition, boys' beliefs about peers changed in response to their social experience. The implications of these findings for children's social development are discussed.

Mapping cardiac physiology and parenting processes in maltreating mother–child dyads.

Child maltreatment (CM) lies on an extreme end of the continuum of parenting-at-risk, and while CM has been linked with a variety of behavioral indicators of dysregulation in children, less is known about how physiological markers of regulatory capacity contribute to this association. The present study examined patterns of mother and child physiological regulation and their relations with observed differences in parenting processes during a structured interaction. Abusing, neglecting, and non-CM mothers and their 3- to 5-year-old children completed a resting baseline and moderately challenging joint task. The structural analysis of social behavior was used to code mother–child interactions while simultaneous measures of respiratory sinus arrhythmia were obtained. Results indicated that physically abusive mothers were more likely to react to children's positive bids for autonomy with strict and hostile control, than either neglecting or non-CM mothers. CM exposure and quality of maternal responding to children's autonomous bids were uniquely associated with lower parasympathetic tone in children. Results provide evidence of neurodevelopmental associations between early CM exposure, the immediate interactive context of parenting, and children's autonomic physiology.

Sexual risk among African American girls: Psychopathology and mother–daughter relationships.

Objective: To examine the associations among mental health problems, maternal monitoring and permissiveness, mother–daughter communication and attachment, and sexual behaviors among African American girls receiving outpatient psychiatric care. Youths with mental health problems report higher rates of HIV-risk behavior than do their peers, and African American girls have higher rates of sexually transmitted infections than do girls of all other racial groups. Method: A sample of 12- to 16-year-old African American girls (N = 266, mean age = 14.46 years) and their female caregivers (73% biological mothers) completed computerized assessments of girls' mental health symptoms, maternal monitoring and permissiveness, and mother–daughter communication and attachment. Girls indicated their sexual risk behaviors (vaginal/anal sex, consistent condom use, number of partners). Results: African American girls who reported clinically significant externalizing problems, more permissive parenting, less open mother–daughter sexual communication, and more frequent mother–daughter communication were more likely to report having had vaginal and/or anal sex. Sexually active girls with greater maternal attachment were less likely to report inconsistent condom use. Conclusions: Findings revealed important risk and protective factors for African American girls in psychiatric care. HIV-prevention programs may be strengthened by improving mother–daughter relationships and communication and by reducing girls' mental health problems.

Infant–mother attachment and children's friendship quality: Maternal mental-state talk as an intervening mechanism.

Utilizing data from the Eunice Kennedy Shriver National Institute of Child Health and Human Development's Study of Early Child Care and Youth Development, we investigated mothers' talk about mental states during play with their 24-month-old children as a mechanism though which infant–mother attachment was associated with children's later friendship quality. A series of repeated measures analyses of covariance indicated that a secure versus avoidant or disorganized infant–mother attachment was associated with more maternal talk about cognitions (but not emotions or desires) at 24 months. Latent growth curve models tested within a structural equation modeling framework revealed indirect effects of infant–mother attachment on observed and mother-reported positive friendship interaction at 54 months and decreases in mother-reported negative friendship interaction from 54 months to 1st grade via maternal cognitive talk at 24 months.

Intimate partner violence moderates the association between mother–infant adrenocortical activity across an emotional challenge.

This study examined the relationship between mother and infant adrenocortical levels and reactivity to an emotion eliciting task. The impact of intimate partner violence (IPV) on these relationships was assessed as a moderator. The sample (n = 702 mother–infant dyads) was racially diverse and from predominantly low-income, rural communities. During a home visit, the dyad’s saliva was sampled before, 20 min, and 40 min after standardized tasks designed to elicit the infant’s emotional arousal and later assayed for cortisol. Mothers completed self-report measures of their partner’s violence, and parenting behaviors were assessed via structured interview and mother–child interactions. In response to the task, infants had positive, and mothers had negative, cortisol slopes. Contrary to expectations, there were no IPV-related differences in mean pretask cortisol levels or reactivity in the mothers or infants. Mother–infant dyads from households characterized by either (1) violence or (2) restrictive and punitive parenting behaviors exhibited correlated cortisol reactivity measured in response to the infant challenge task. The findings suggest that social contextual features of the early caregiving environment may influence individual differences in the coordination between maternal and infant adrenocortical reactivity.

Parental beliefs, infant temperament, and marital quality: Associations with infant–mother and infant–father attachment.

The present research examined parental beliefs about the importance of the paternal caregiving role, mothers’ and fathers’ reports of infant temperament, and observed marital quality as predictors of infant–mother and infant–father attachment security, over and above the effects of parental sensitivity. Infants’ attachment security to mothers and fathers were observed in the Strange Situation at 12 and 13 months, respectively (N = 62 two-parent families). Hierarchical regression models revealed that mothers who viewed the paternal caregiving role as important were less likely to have securely attached infants, but only when infant fussiness was high. In addition, fathers who viewed the paternal caregiving role as important were more likely to have securely attached infants, but only when infants’ fussiness or marital quality was high.
